中外合资企业跨文化管理的"钻石结构"模型研究--大亚湾核电跨文化管理的探索 总被引:3,自引:0,他引:3
本文在继承传统跨文化管理--从国家文化角度分析管理问题的基础上,重点从微观层面出发建立了一个跨文化管理的"钻石结构"模型,并运用这个结构模型来具体分析了大亚湾核电跨文化管理的实践活动,并对大亚湾核电跨文化管理的主要措施进行了探讨,希望这些结论能够对未来中外合资合作企业进行跨文化管理提供有益的参考和借鉴作用. 相似文献

Variable selection is an important issue in all regression analysis, and in this article, we investigate the simultaneous variable selection in joint location and scale models of the skew-t-normal distribution when the dataset under consideration involves heavy tail and asymmetric outcomes. We propose a unified penalized likelihood method which can simultaneously select significant variables in the location and scale models. Furthermore, the proposed variable selection method can simultaneously perform parameter estimation and variable selection in the location and scale models. With appropriate selection of the tuning parameters, we establish the consistency and the oracle property of the regularized estimators. These estimators are compared by simulation studies. 相似文献

In the lifetime experiments, the joint censoring scheme is useful for planning comparative purposes of two identical products manufactured coming from different lines. In this article, we will confine ourselves to the data obtained by conducting a joint progressive Type II censoring scheme on the basis of the two combined samples selected from the two lines. Moreover, it is supposed that the distributions of lifetimes of the two products satisfy in a proportional hazard model. A general form for the distributions is considered, and we tackle the problem of obtaining Bayes estimates under the squared error and linear-exponential (LINEX) loss functions. As a special case, the Weibull distribution is discussed in more detail. Finally, the estimated risks of the various estimators obtained are compared using the Monte Carlo method. 相似文献

The gamma distribution has been discussed by many authors. This article proposes an exact confidence region for the parameters of a two-parameter gamma distribution. The result is based on the fact that the percentiles of the F-distribution, with equal degrees of freedom k, are monotonic in k. 相似文献

在集体意思决定的过程中,对违法决议的赞成票数远远超过了决议通过的最低门槛,出现了过剩原因并且存在过失的场合,如何对个人进行归因与归责是现实对刑法理论提出的一项重大挑战。在国家机关或企事业单位的决议场合,进行因果关系的假定判断时,应当以实际存在的具体事实为基础,而非把各个成员的态度作划一的理解。对此,应当根据当时讨论、决议的具体情况,考察各个成员的态度实际上对其他人发挥了怎样的作用。而其他团体进行不具有强制力的决议或匿名投票的场合,则可通过共犯原理将每个成员作为教唆或帮助犯处理。 相似文献

In this paper, when a jointly Type-II censored sample arising from k independent exponential populations is available, the conditional MLEs of the k exponential mean parameters are derived. The moment generating functions and the exact densities of these MLEs are obtained using which exact confidence intervals are developed for the parameters. Moreover, approximate confidence intervals based on the asymptotic normality of the MLEs and credible confidence regions from a Bayesian viewpoint are also discussed. An empirical comparison of the exact, approximate, bootstrap, and Bayesian intervals is also made in terms of coverage probabilities. Finally, an example is presented in order to illustrate all the methods of inference developed here. 相似文献

In this article, we consider sequences of i.i.d. random variables and, under suitable conditions on the (common) distribution function, we prove large deviation principles for sequences of maxima, minima and pairs formed by maxima and minima. The i.i.d. random variables can be either unbounded or bounded; in the first case maxima and minima have to be suitably normalized. 相似文献

1876--1879年,华北晋、豫、陕、鲁、直等省发生了特大旱灾,而其中山西省灾情最为严重。救灾过程中,政府的“官赈”、民间的“商赈”以及西方来华教会的“教赈”,不但各有表现,而且还遥相呼应,客观上推动了传统慈善事业的近代化。 相似文献

This article focuses on the conditional density of a scalar response variable given a random variable taking values in a semimetric space. The local linear estimators of the conditional density and its derivative are considered. It is assumed that the observations form a stationary α-mixing sequence. Under some regularity conditions, the joint asymptotic normality of the estimators of the conditional density and its derivative is established. The result confirms the prospect in Rachdi et al. (2014) and can be applied in time-series analysis to make predictions and build confidence intervals. The finite-sample behavior of the estimator is investigated by simulations as well. 相似文献

We jointly model longitudinal values of a psychometric test and diagnosis of dementia. The model is based on a continuous-time
latent process representing cognitive ability. The link between the latent process and the observations is modeled in two
phases. Intermediate variables are noisy observations of the latent process; scores of the psychometric test and diagnosis
of dementia are obtained by categorizing these intermediate variables. We propose maximum likelihood inference for this model
and we propose algorithms for performing this task. We estimated the parameters of such a model using the data of the 5 year
follow-up of the PAQUID study. In particular this analysis yielded interesting results about the effect of educational level
on both latent cognitive ability and specific performance in the mini mental test examination. The predictive ability of the
model is illustrated by predicting diagnosis of dementia at the 8 year follow-up of the PAQUID study based on the information
from the first 5 years. 相似文献
